# DVI previewers
EmTeX for PCs running MS-DOS or OS/2, MiKTeX and XEmTeX for PCs running Windows and OzTeX for the Macintosh, all come with previewers that can be used on those platforms. EmTeX's previewer can also be run under Windows 3.1.
Commercial PC TeX packages (see [commercial vendors](FAQ-commercial.md)) have good previewers for PCs running Windows, or for Macintoshes.
For Unix systems, there is one
canonical viewer, `xdvi`.
`Xdvik` is a version of `xdvi` using the
`web2c` libraries; it is now built from the same distribution
as `xdvi`. The TeX Live distributions for Unix systems
include a version of `xdvik`.
Alternatives to previewing include
- conversion to
similar ASCII text (see
[converting to ASCII](FAQ-toascii.md)) and using a conventional text viewer to look at that,
- generating a PostScript version of your document and viewing it
with a [`ghostscript`](http://www.ghostscript.com/)-based previewer (see [previewing PostScript files](FAQ-PSpreview.md)), and
- generating PDF output, and viewing that with
`Acrobat` `Reader` or one of the substitutes for that.
